DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for forming a precedent partition in a ceiling from the back surface of an upper slab.

[0002]

2. Description of the Related Art Conventionally, a partition wall for partitioning a living room or the like is often formed from the back surface of an upper slab to the slab surface. Such a partition wall is made of a steel wall base material (stud) on a floor on which a slab surface is formed, based on a black ink or a finished black ink which is inked on the slab surface.
It is formed by assembling a lower board or an upper board. Further, in the portion to be located in the ceiling, the steel wall base material is arranged in consideration of the connection between the steel wall base material and equipment-related members such as pipes and ducts running around the ceiling. After that, a surface material such as a gypsum board or rib lath is attached to the steel wall base material, and a required coating process is performed to form a fire-resistant wall structure or a sound insulation wall structure. After the partition walls are formed in this way, the process proceeds to the next ceiling construction stage.

[0003]

However, in the case of forming a partition wall of a building having many small rooms which are finely divided, a large number of portions between the equipment-related members arranged in the ceiling and the steel wall base material increase. For this reason, it is necessary to perform processing such as cutting off the steel wall base material to be passed in the vertical direction of the floor while responding to the above-mentioned arrangement at the site, and a large amount of offcuts are generated, which tends to be uneconomical. Further, in the connection portion, a steel wall base material is assembled around equipment-related members (such as pipes and ducts), and after covering the surface materials and the like, coating work is performed to enhance fire resistance and sound insulation. . For this reason, there also arises a problem that the equipment-related materials are in the way and the coating work is likely to be difficult.

[0004] In view of the above circumstances, the present invention forms a part of a partition wall having an equipment sleeve frame in a part inside the ceiling as a down wall in advance, and coats the down wall before placing the equipment related members. Be able to apply
An object of the present invention is to make it possible to use a fixed-length steel wall base material when forming the falling wall, to economically use the steel wall base material, and to improve workability of fireproof and sound insulation work. The purpose is to:

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has a structure in which a ceiling inner lower wall of a partition wall is provided from a rear surface of an upper slab to a position above a ceiling finishing height. After mounting the equipment sleeve frame to the frame, and covering the surface material, perform the required coating process to form a ceiling inner falling wall, the ceiling inner lower wall equipment sleeve to the ceiling piping duct etc. The above-mentioned problem is solved by installing through the equipment-related members.

[0006]

According to the present invention, at the place where the partition wall is to be installed, first, a descending wall having an equipment sleeve frame is formed in a portion inside the ceiling. Then, work is performed to apply a fireproof coating or a sound insulation coating to the descending wall. Thereafter, by passing the equipment-related member through the equipment sleeve that opens to the lower wall, a partition wall is formed in a portion inside the ceiling.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described in detail based on one embodiment shown in FIGS. FIGS. 1 and 2 show a completed partition wall 1, which is composed of an upper slab a
A lower wall 2 extending between a floor deck b serving as a back surface of the lower wall and a position e rising upward from the ceiling finishing height c by a required amount d (about 130 mm), and a slab surface ( (Floor surface) f.

As shown in FIG. 2, a falling wall 2 is provided between a runner (steel [mold member] 4) fixed by an anchor pin 3 along an upper slab a and a runner 5 located at a lower end side. There is a shaft assembly in which a steel wall base material (stud: C-shaped member) 6 is arranged and the steel wall base material 6 is welded to the runners 4 and 5 (welded portions are indicated by marks in the figure). ), This is supported by a brace 7 lowered from the upper slab a side, and a face material 8 such as a rib lath is provided on each side surface. The face material 8 is sprayed with rock wool mortar 9 to form a fire-resistant wall structure. Partition wall body 3
Is a runner (steel [mold member]) welded to the lower end joint member 10 located at the lower end of the falling wall 2 as shown in FIG.
A steel wall base material (C-shaped member) 13 is disposed between the runner 11 and the runner 12 fixed to the slab surface f, and the steel wall base material 13 and the runners 11 and 12 are welded to each other. And
A lower board 14 and an upper board 15 made of a gypsum board are provided on both sides. Then, as shown in FIG. 1, rock wool mortar 16 is sprayed and covers the continuous portion between the descending wall 2 and the partition wall main body 3.

The partition wall 1 having the above structure is formed as follows. (Formation of falling wall) First, black ink and finishing ink of the partition wall are inked on the slab surface, and air conditioning, electricity,
Marking of equipment-related members such as piping for disaster prevention is also performed on the slab surface. The runners 4 and 5 described above and steel are used between the back surface of the upper slab (floor deck b) and the above position, with the lower end being a position raised by about 130 mm from the ceiling finishing height, based on the black ink of the partition wall. The lower wall is assembled with the wall base material 6 and the lower end joining material 10, and the equipment sleeve frame 18 is installed in accordance with the shaft assembly 17 based on the ground color of the equipment-related member (see FIG. 3). Frame 1
When 7 is completed, a face material 8 made of rib brass is stretched, and the whole is sprayed with rock wool mortar 9 to cover, thereby obtaining the falling wall 2 (see FIG. 4). The material and the covering material as the face material 8 are appropriately selected according to the performance set for the partition wall. In addition, in order to facilitate the explanation, FIG. 4 shows a state in which the rock wool mortar is sprayed only on the specific descending wall, but the spraying of the rock wool mortar is also applied to the floor deck, the steel beam and the like. Is what is done.

(Installation of Related Equipment Members) After the falling wall 2 is completed as described above, various equipment related members such as pipes and ducts are carried to the floor, and these are passed through the equipment sleeve 19 of the falling wall 2. Install at the required position (Fig. 5). In these operations, since the partition wall main body is not formed on the slab surface, the members are carried using a cart such as an automatic guided vehicle, and the installation is performed using equipment such as a rolling tower and a work lift. . Then, heat insulation work will be performed on those necessary according to the type of equipment-related members.

(Formation of Partition Wall Body) After the installation of the equipment-related members is completed, the partition wall body is formed. As described above, the partition body is framed by the runners 11 and 12 and the steel wall base material 13 between the lower end of the falling wall 2 and the slab surface f, and a lower board and an upper board are stretched on both sides of the frame. As a result, the partition wall main body 3 is obtained (see FIG. 1), and the partition wall 1 is completed by forming the above-mentioned descending wall 2 and the partition wall main body 3 continuous therewith. Thereafter, rock wool mortar 16 is sprayed on a continuous portion between the descending wall 2 and the partition wall main body 3.

As described above, according to the present invention,
From the back side of the upper slab to the upper position of the ceiling finishing height, perform the frame assembly of the ceiling lowering wall in the partition wall, attach the equipment sleeve frame to the frame, and stretch the surface material,
A required covering process is performed to form a ceiling inner falling wall, and the equipment sleeve of the ceiling lower wall is installed through a facility-related member such as a ceiling piping duct.

[0013] In the position where the partition wall is provided, in the portion inside the ceiling, the lower wall is formed with the lower position above the ceiling finishing height as a lower end, and the wall is formed separately from the partition wall main body. Eliminating the need to adjust the length of the long steel plate wall base material up to the length of the installation-related members, and making the height of the falling wall constant,
As a steel wall base material over the height direction, it is possible to use a material cut in advance to a fixed length, especially when many small rooms with a fixed ceiling height are set. , Members can be used very effectively. Also, if the dimensions of steel wall base materials and face materials are constant,
It is possible to use an off-the-shelf product having a certain size, and it is possible to reduce the cost of cleaning and the cost of treating industrial waste, by minimizing the generation of residual materials such as cut-off.

Further, before the installation of the equipment-related members such as pipes and ducts, the falling walls through which these members are disposed are completed, so that the ceiling-wall is not disturbed by the equipment-related members. Fireproofing and sound insulation work can be performed on the inner part, which facilitates the work. In addition, equipment related members can be loaded and installed on a large floor before the partition wall body is formed, making it possible to use equipment such as automatic guided vehicles, large transport vehicles, rolling towers, work lifts, etc. This makes it possible to carry out the work in a short time, and has an effect extremely excellent in practicality.
